From the current color TV market, energy-saving, high-definition, ultra-thin and ultra-light flat-panel TVs have become the mainstream of the market, especially flat-panel TVs that use LED backlights, which are hot in the market. Then, is the TV with LED backlight called LED TV? What conditions are LED TV? What should you pay attention to when purchasing LED TV? Next, the author will reveal the secret of LED and then Help everyone to recruit, teach you to buy LED TV, a friend in need may wish to take a look.
First, look at contrast and black expression. In fact, many LCD TVs have more or less disadvantages in black performance, and led backlight TV can automatically adjust the brightness level of LED, broaden the performance of contrast, improve the black depth, black expression is more profound, Therefore, the advantage of black performance has become one of the signs of a good LED TV. When purchasing, you may wish to directly compare the expressive power of the TV to the black screen.
Second, look at the color gamut expressiveness. It can be judged roughly like this. For example, it seems to be the reversal effect of the photo. Before the reversal, the color will be richer and clearer. If the color gamut is not wide, the picture will be as eclipsed as the photo that needs to be reversed. The color is not in place.
Third, look at the dynamic picture display effect. LED TV itself has advantages over ordinary LCDs in terms of reaction speed due to the advantages of backlight. It can be distinguished by providing parameter data-screen refresh rate and visually watching dynamic images. For example, you can find a guide to play videos such as racing cars and ball games. For example, the T-model show can be used, and the inferior TV can't bear the dynamic picture of the model walking up and down. The screen refresh rate, the current TV screen refresh rate in the market ranged from 100 Hz to 200 Hz, the higher the screen refresh rate, the more stable and clear the picture performance.
Fourth, look at the interface. The reason why I mentioned the interface in the high-definition TV purchase strategy is because I think that if you want to enjoy high-definition video, you have to look at the film source, connect the computer, connect the DVD, and connect to the PS3. These external functions must be considered. More than a few HDMI interfaces will never suffer. However, buying LED TVs can not make slim and confused eyes. Now many manufacturers are looking for slim, many interfaces are external, pay attention to choose a built-in interface. The TV is also very important.
Everyone knows the above 4 steps, I believe that the brand of LED TV is no longer a problem.
